Subject Re: Adding a new node
Date Mon, 09 May 2011 06:11:01 GMT
Thanks for the pointer.  I restarted entire cluster and started nodes at the
same time. However, I still see the issue.  The view is not consistant. Am
running 0.7.5.
In general, if a node with bad ring view starts first, then I guess the
restart also doesnt help as it might be propagating its view.  Is this
assumption correct?
